If I set Windows' "Make text bigger" setting to something > 100%, then printing http://crisal.io/tmp/cross-origin-iframe-simple.html shows the wrong scale.

Usually this happened because the frontend never specified any zoom for
these, but once we started honoring the system scale factor, well...

For printing, we should use the print scale factor to determine
css-to-device scale. I assume text scale we could keep, but that doesn't
seem worth it and it seems preferable to keep stuff consistent between
zoom and OS text scale / zoom.

I don't know of another reasonable way to test this other than this (and
it kinda sucks), but I'm open to ideas.
